Valve has released a new, still-in-beta version of the wildly popular online shooter Counter-Strike: Source, adding in new achievements, "domination and revenge" systems and other improvements that don't muck with the game's core experience.

What the new Counter-Strike: Source does appear to bring with it are a handful of features seen in other Valve-developed games. The domination and revenge system sounds reminiscent of the same feature seen in Team Fortress 2, not much more than a chance to feel good about racking up kill streaks against players (or breaking someone else's kill streak).

There are 144 new Steam achievements, a look at lifetime and match-specific player stats, as well as a few visual tweaks and Source engine updates. Valve says the beta will run for an unspecified limited time and that developer Hidden Path was tapped to help with the changes.
